LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 515,590, dated February27, 1894.

Applicationfiled June 23, 1893.

To whom it may concern.-

Be it known that I, JOHANNES EMANUEL LAGERMAN, a subject of the King ofSweden and Norway, residing at Husqvarna, Sweden,

have invented certain new and useful Improvements in Apparatus forDistributing and Feeding Oil, of which the following is a specification.

This invention relates to an apparatus for re distributing oil from acentral point to auumber of bearings located at separate points withinpracticable distance from the central reservoir; and the object of theinvention is to provide an apparatus which is adapted to feed heavy aswell as thin oils in regulated quantities and at suitable intervals oftime to any desired number of bearings, as, for example, the apparatusmay be adapted to the oiling of the cylinders of a locomotive and to theseveralbearings of the moving parts thereof, or it may be adapted to theoiling of the cylinder and crank bearings of a stationary engine andtothe various journal boxes for the shafts driven by said engine.

The particular construction of the apparatus may be considerably varied,but I have shown in the accompanying drawings an apparatus whichcomprises an intermittently driven. shaft, which is made to operate twosets of plungers, one set of which is utilized to withdraw oil from areservoir into a pump chamber, and the second set of which is utilizedto force oil from said chamber into a supply pipe or tube, said supplypipe or tube being adapted to deliver the oil thus fed into a header ormain distributing pipe, from which branchpipes are run to the severalbearings which are to be lubricated. I

an eccentric on the line 10-l0 of Fig.6. Fig.

11 is a diagrammatic view showing a header with branch pipe connectionsand one branch pipe partly broken away for supplying oil to a bearingshown in end elevation. Figs. 12

to 16 inclusive are detail views of a nozzle whereby a lubricant may befed in regulable quantities.

In the drawings, 16 represents a base or bed which is chambered toprovide oil receptacles, plunger openings, pump chambers and ports, andwhich serves also for supporting the shafts and other moving parts ofthe apparatus. Upon the front side of said bed are arranged the uprightreservoirs 17,18, which are in communication with the oil chambers 19,20. The body of said casting is longitudinally bored providing chamberswithin which work plungers and valve stems as hereinafter described.Said bed piece is also vertically bored to provide pump chambers 21,which intersect the valve chambers and terminate in the plungerchambers.

By reference to Figs. 1 to at inclusive it will be seen that there areprovided three plunger chambers, three valve chambers and acorresponding number of pump chambers. One of said valve chamberscommunicates with the oil chamber 19 and two of them communicate withthe oil chamber 20. It will also be seen that the valve chamber andplunger chamber which are in communication with the oil chamber 19 arelarger than those which are in communication with the oil chamber 20,and thereby the apparatus is adapted to feed different kinds of oil. '10accelerate the flow of the oil a weight W'(Fig. 4) may be employed.

22 refers to a plunger for feeding the oil from chamber 19, and 23 and23 refer to plungers for feeding the oil from chamber 20. Said plungersare actuated from rocker boxes 24: which are ecccntrically pivoted uponrock shaft 25 journaled in the sides of the bed. An 5 intermittentmotion is communicated to said rocker boxes through eccentrics 26 on ashaft 27. Said shaft 27 has a step by step rotative movementcommunicated to it through a ratchet wheel 28 carried thereon, saidratchet being advanced step by step through a pawl 29 carried upon arock arm 30, the latter being oscillated in any convenient way, as, forexample, by an eccentric or from a crank (not shown). The rocker boxes24 and cams 26 are thus driven intermittently, a single actuation of thearm 30 advancing them through the arc of a circle corresponding to thelength of the are described by the stroke of the arm 30. plungers 22 and23 may be varied by varying the connection to the arm or by varying theset of the eccentrics 26 the stroke of the plungers 23 may be variedindependently.

Arranged above plunger 22 is a valve 31 and above the plungers 23, 23are two valves 32 of similar construction, one of which is shown in Fig.3 in side elevation. Said valves have the L-shaped passages 33, one endof which opens into the respective chambers 19 and 20, and the innerends of which are adapted to register with the pump chambers 21. Each ofthe valves is also provided with a transverse port 34, and in oneposition of the valve said port will open communication between the twoends of the pump chamber 21. The delivery pipes 35 communicate with theupper ends of said chambers, and deliver to headers 36, one of which isshown in Fig. 11. Said headers may be provided with a series of nipples37 to which are attached pipes 38 leading to separate bearings, such forexample as the bearing 39 shown in said Fig. 11. It will be understoodthat these branch pipes 38 deliver oil to a steam cylinder or to abearing of any form and at any distance to which it is practicable tocarry the oil through a pipe and deliver it by the pulsations of a pump.

Referring again to the oil forcing mechanism shown in the first tenfigures of the drawings, the valves are connected at their outer ends tovibrating arms 40, which are keyed at their lower ends upon a rock shaft41, said rock shaft being rocked by a yoke 42 whose bifurcations embracean eccentric 43 on the shaft 27. The box 24 to which piston 22 issecured has an upwardly projecting ear through which car is pivotallysecured a rock shaft 44, said rock shaft having rigidly secured to itsprojecting ends dogs 45 and 46. The dog 45 rides upon a cam 47 securedupon the side of the ratchet wheel 28 and when riding upon the high partof the cam elevates the dog 46 above the path of a striking block 48upon a projection 30 of the rock arm 30. When the dog 45 drops upon thelow part 47' of the cam 47 the dog 46 is lowered into the path of thestriking block 48 and receives therefrom a blow equal to the full forceof the stroke of the engine, thereby causing the plunger to make acomplete outward stroke by a single impulse. Upon the following strokeof the rock arm 30, the dog 45 will have risen upon the high part of thecam 47 and the cam 26 on shaft 27 will rock' the box 24 upon shaft 25and withdraw the plunger to the outward limit of its stroke, preparatoryfor a repetition of the same action.

The length of stroke of the The plungers which force the oil fed fromchamber 20 move alternately back and forth with each step of the pawland ratchet thus providing a constant feed, while the plunger 22operates only once during a complete revolution of the ratchet as theparts are arranged, thus making an intermitted feed.

Referring to Figs. 10 to 15 inclusive, attention is called to a safetyvalve 49 secured on the header 36 by the weighted lever 50; also to theparticular construction of the nozzle of the pipe 38, said pipe beingslotted to receive a wedge 51 of a perforated disk 52, said perforationbeing adjusted with the aperture in the screw threaded nipple 53, whichnipple is adapted to turn upon the screw threaded end of pipe 38. Thesupply of oil may be regulated to any desired quantity at each of theseveral bearings, or cut off entirely by turning the nipple of the feednozzle, thus regulating the quantity of oil used at each lubricatingpoint and greatly reducing the waste of the lubricant.

Vhile I have described my invention as adapted to the feeding of oilfrom two separate oil chambers, it is obvious that the principalfeatures thereof may be applied to the feedingof oil from a singlereservoir. The provision of separate reservoirs adapts the apparatusforfeeding divers kinds of oil to the bearings to which they arerespectively adapted, and the provision of two plnngers receiving oilfrom the same or separate reservoirs but delivering it through separatepipes adapts the same apparatus for supplying oil to engines of diversecharacter, as, for example, one of said plungers may force oil to a highpressure and the other to a low pressure cylinder, thus properlylubricating them; whereas, if it were attempted to lubricate both ofsaid cylinders by a single forcing apparatus, the low pressure cylinderwould take all the oil.

The object in arranging one of the plungers so that it may be driven tothe end of its chamber by a single impulse instead of being forced inslowly -by a cam is that where the continuous feed is employed thebearings nearest the feeder will receive the most, if not all the oil,but where the oil is fed by the plunger having the quick, powerfulstroke it is delivered to the several bearin gs, those most remotereceiving asufiicient supply. The latter form of the apparatus is bestadapted to a pipe system wherein large pipes are employed havingbearings located at a distance from the feeder.
